Is there a pin-compatible replacement for RLP25FEER020?

Yes, several pin-compatible replacements in the same 2512 package exist. RLP25FEGR020 is a direct upgrade. Other options like Milliohm's LR2512D-3W-20mR-1% are also pin-compatible but require checking for specific qualifications like AEC-Q200.

What risks should I check before replacing RLP25FEER020?

When replacing RLP25FEER020, primarily check the power rating and automotive (AEC-Q200) qualification. While upgrades to a higher power rating (e.g., 3W) are generally safe, ensure the replacement meets the same or better TCR and tolerance. If used in an automotive application, AEC-Q200 is critical.
